Conversion is by delta demodulation, using the Continuously Variable Slope (CVSD) method of demodulation. While signals are patible with other CVSD circuits, the internal design is unique. The analog loop filters have been replaced by digital filters which use very low power and require no external timing ponents. This digital approach allows...
